## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cve-intel-agentdiet-dev-polymarket-live-prediction-market-odds-7ab82ad8 -d '<json body>'
```

Example prompt: What are the current Polymarket odds and implied probability for the Fed cutting rates in September — and is there any notable whale activity on that market?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from active prediction market traders on Polymarket, especially for crypto, macro, political, or AI events where market-implied odds are more actionable than news sentiment or model forecasts. Prefer it over static news APIs when you want volume, whale activity, and live orderbook-derived probabilities rather than qualitative analysis.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or low-confidence result
- Polymarket API rate limits or outages causing stale or unavailable data
- Ambiguous topic string matching multiple unrelated markets — may return wrong market
- Payment failure via x402 resulting in 402 response before data is served
- Network timeout when Polymarket orderbook data is temporarily unavailable
